V Variants The 737 models can be divided into three generations, including nine major variants. The "Original" models consist of the 737-100, 737-200/-200 Advanced. The "Classic" models consist of the 737-300, 737-400, and 737-500. The "Next Generation" variants consist of the 737-600, 737-700/-700ER, 737-800, and 737-900/-900ER. Of these nine variants, many feature additional versions such as the T-43, which was a modified Boeing 737-200 used by the United States Air Force (USAF). v Lufthansa 737-100 737 Original series 737-100 The initial model was the 737-100. It was launched in February 1965. The -100 was rolled out on January 17, 1967, had its first flight on April 9, 1967 and entered service with Lufthansa in February 1968. The aircraft is the smallest variant of the 737. A total of 30 737-100s were ordered and delivered; the final commercial delivery took place on October 31, 1969 to Malaysia–Singapore Airlines. No 737-100s remain in commercial service. The original Boeing prototype, last operated by NASA and retired more than 30 years after its maiden flight, is on exhibit in the Museum of Flight in Seattle. 737-200 The 737-200 is a 737-100 with an extended fuselage, launched by an order from United Airlines in 1965. The -200 was rolled out on June 29, 1967, and entered service at United in April 1968. The 737-200 Advanced is an improved version of the -200, introduced into service by All Nippon Airways on May 20, 1971. The -200 Advanced has improved aerodynamics, automatic wheel brakes, more powerful engines, more fuel capacity, and longer range than the -100. Boeing also provided the 737-200C (Cargo), which allowed for conversion between passenger and cargo use and the 737-200QC (Quick Change), which facilitated a rapid conversion between roles. The 1,095th and last delivery of a -200 series aircraft was in August 1988 to Xiamen Airlines. Many 737-200s have been phased out or replaced by newer 737 versions. In July 2015, there were a combined 99 Boeing 737-200s in service, mostly with "second and third tier" airlines, and those of developing nations. Boeing B737 June 2017 www.alliance-airways.net 3 ! 7
